"Set for this Tab" Stopped persisting between sessions+ temp workaround using bookmark

[piecevcake]

Some questions and idea on this issue, which you have mentioned in issues 13 and 17

Firefox (not updated since 74), Windows 8.1

"This Tab" used to be persistent, so am I guessing right that FF renumbering tab IDs between sessions has only recently started?

If so,

1. Do you know which version changed this?
2. are you aware of any reason they have done this, or is it just another new bug they have added?

Suggestion: can I suggest you update the known issues on your addon page to point out the bug , add a link to a bug report about it, and encourage readers to click the link and upvote the bug report? (I have seen that done on other addon pages :)

(same for the PDF and moz pages bugs - there are years of bug reports complaining about them, nothing is done)

I noticed today (after TRT stopped working and I disable/re-renabled it) that

1. yes all my dozens of carefully retitiled "this tab"s are gone

2. a tab I opened today is called tab 1! (Does this mean that FF has renumbered all my tab IDs, in the same session, every time I open a tab, or has this number been allocated to fill a closed tab number? There must be some system... I think I'll leave that to you)

3. Another tab I created today (by duplicating another tab) is 315.

4. New just now: 3 tabs I retitled in this session using both "exact match" and "This Tab", all lost their titles. But the titles are still in the saved titles box. (I'll leave that for later - see if it self-resolves...)

Workaround (maybe a clue to fix it too?) Before loading the tab, bookmark it! The old name is then offered as an option in the retitle dialog. :)) Tree Tabs which I use, can bookmark a whole group imported between profiles (because Tree Tabs imports them unloaded ) so I can retrieve all titles. (doesnt work for addons like Onetab and Tree Style Tabs, which dont load tabs discarded.)
